The Effect of Synchronizing the Human Heart Rhythm with Geomagnetic Field Variations: Are There Distinguished Frequencies?

Ongoing research continues to explore the phenomenology of the effect of synchronization between oscillations of a human resting heart rate and variations of the geomagnetic field in the period range 3–40 minutes. A total of 508 experiments have been conducted for the period 2012–2023 (each experiment lasted 100–120 minutes) to monitor the minute indicators of heart rate for three healthy women (55, 45, and 30 years old). 328, 113, and 67 measurements were made, respectively. The results indicate that, for each of these three volunteers, approximately 60% of the experiments yielded a wavelet spectrum of heart rate values that closely resembled the spectrum of synchronous variations of at least one of the horizontal components of the geomagnetic field (X or Y). Additionally, within the investigated frequency range of 3–40 minutes, three subbands were identified and in these sub-bands, the degree of synchrony of oscillations was maximal: 3.5 minutes, 10–12 minutes and 33–36 minutes. It can be concluded that the effect of biogeosynchronization is not uniformly implemented over the entire range from 3 to 40 minutes, but it is mainly evident in these sub-bands.
